One way to start, a canning/gardening group.

That way you all have sufficient food put back to start.

If enough hunt, more food and firearms.

You don’t have to agree about everything,  fact is it can help to disagree and get a fresh perspective.

Many years ago, in my first group we had a hippie chick who didn’t like guns.  Why was she with us? Because she also understood their usefulness,  at least in someone else’s hands. She was also a herbal medicine teacher, medieval living specialist and taught longbow and other primitive weapons construction.

It was mutually beneficial,  and a unique perspective that we wouldn’t have gotten anywhere else.

mutual respect goes a long ways.
